Creating JSON Extracts in Supabase

How to upload and extract JSON using Postgres trigger functions in Supabase.
I loved my database courses in college. 20 years ago I could have written you a perfectly normalized relational database with a binder full of DB2 SQL queries that looked like magic. Since then much of that knowledge has begun to escape me as I haven’t had a strong desire to delve back into databases. Not because I don’t find them fascinating. But because getting them up correctly can be a pain.
Fast-forward a few years and DB2 has been superseded by Postgres and thanks to Supabase making relational databases super easy to set-up I find myself reaching back for that DB structures knowledge once again. Only now we’ll be working with something that didn’t exist back then: JSON.
In this post I’ll explain how to upload and extract JSON data into rows in a Postgres database using SvelteKit and Supabase. And though processing data this way seems like it would be a fairly common task, I wasn’t able to find a guide online describing how to do this. As a result, I thought it worthwhile to jot down how to do it.
